Summary

Convert any angle from gradians (grad/gon) to radians using the formula radians = gradians × π/200, with a step-by-step breakdown and common angle reference table.

How it works

  1. Enter an angle in gradians (grad or gon) in the input field.
  2. The converter applies the formula: radians = gradians × (π / 200).
  3. The result is displayed as a decimal and as a multiple of π.
  4. A step-by-step breakdown shows each stage of the calculation.
  5. Click any row in the reference table to load that angle into the converter.

Use cases

  • Converting gradian angles from surveying equipment to radians for computation.
  • Checking angle equivalents when working in civil engineering or geodesy.
  • Understanding the relationship between the gradian and radian systems.
  • Verifying manual conversions of common right-angle multiples.
  • Teaching or learning the gradian unit used in European surveying.
  • Preparing gradian measurements for use in trigonometric functions.
